WIRE-STpAY-IVIAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 721,567, dated February 24, 1903.`

Application filed November 2, 1901. Serial No. 80,957. (No model.) i

To @ZZ whom t may concern.:

Be it known that we, JAMEsKELI-.EY and PETTIs A. REID, citizens of the United States, residing at Richmond, in the county of Wayne and State of Indiana, have invented certain new and useful Improvements in Wire-Stay- Making Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make anduse thesame.

This invention relates to machines for mak-V ing wire stays or cross-wires designed for attachment to aseries of strand-wires in the manufacture of wire fencing or fabrics.

The principal object'of the invention is to provide a highly-efficient machine for rapidly producing uniform stays or pickets consisting of wires .having at suitable intervals therein bent portions or loops 'adapted to be wrapped or coiled about the strand-wires for attachment of the stays.

A further object is to provideV means fo forming said stays withtheir several loops in substantial alinement, the two. members of each loop lying in the same transverse plane and theintermediate portions of the stays diverging or extending, preferably, from and to corresponding members of adjacent loops, as illustrated in Figures 2l to'23, inclusive, herein, which construction combines uniformity and general straightness of the separate stays, with capability of the latter to be placed upon or against a series of strand-wires with bothmembers of-each loop contacting with one of said wires, whereby theloops may be twisted about the strand-wires without first bending them to one side or the other of the stay or turning the stayasa whole before beginning the twisting operation, which is obviously advantageous.

The invention will first be hereinaftermore particularly' described with reference to the accompanying drawings, which form a part of this specification, an'dthen pointed out in the claims following this description.

In said drawings, in which similar parts in the several views are designated by corresponding letters of reference, Fig. lis a front elevation of a wire-stay-making machine embodying my invention, the parts being represented in the relative positions assumed immediately after delivery of a wire and prior to the operation of forming the same'into a stay. Fig. 2 is a plan view of the same, the wire-feeding device being removed. Fig. 3 is a' plan view of the said wire-feeding device. Fig. 4 represents a vertical cross-section taken on line 1V IV of Fig. l. Fig. 5 is a detail view of the lever which actuates the needles or loopbending devices and operative cam for said lever. Fig. 6 is a similar view of the wire-grabber-actuating lever and itsoperative cam. Fig. 7 is a partial vertical cross-section of the machine, on an enlarged scale, the parts being represented in the positions assumed during the act of bending portions of a wirein between the looppressing clamps or jaws for the purpose of forming the loops. Fig. 8 is a'detail view of a ratchet device for controlling the wire-feeding device. Fig. 9 is a detail'perspective view of a member of the said feeding device. Fig.'l0is a fragmentary detail view in front elevation, showing the slidable loop-pressing clamps Abrought together and about to be forced by their actuating member or rocker-cam into closer contact to compress the loops of the stay previouslyformed between them, the dotted lines indicating the position of said rocker-cam and its operating-roller immediately before throw in a 'direction to bring the said clamps together. Figs. ll and l2 are fragmentary detail views, in vertical cross section and plan, respectively, showing the operation of withdrawing or ejecting the finished stay from the machine. Fig.4 13 is a detail view, in front elevation, oftwoj adjacent clamps and an interarranged needle, showing the operation of bending intermediate portions of the wire in between the clamps while the latter move inwardly or together. Fig. 14 is a similar view showing the clamps closed or brought t0- gether and the needle raised to escape the same. Fig. 15 is a detail view, in end elevation, of one of the clamps, ytogether withthe forked ornotched end of a push-rod for operating an eccentric device to permit a movable face portion or plate in one of the sides or faces of said clamp to recede or move inward to release the loop of the stay pressed between adjacent clamps.

IOO

Fig. 16 is a plan view of said clamp and push-rod. Fig. 17 is also a plan View of said clamp and push-rod, showing, partly in dotted lines, the rod in the act of operating the said movable face-plate to release the loop. Fig. 18 is a bottom view of one of the clamps. Fig. 19 is a detail perspective view of one of the driving-shafts with its several cranks and cams in proper relative positions thereon. Fig. 20 is a detail View of alever which actuates mechanism for forcing the wire into proper position upon the clamps prior to the operation of forming the same into a stay and operatingcam for said lever. Figs. 2l and 22 are front and plan elevations, respectively, of a finished stay produced by the machine herein illustrated; and Fig. 23 represents an enlarged end elevation of said stay.

Preliminarily to a more detailed description it may be stated that in carrying our invention into effect the wires which are to be formed into stays or pickets being first cut int-o proper lengths are successively delivered upon or against a series of alternately separating and closing clamps orjaws, which prior to each stay forming operation are caused to separate at preferably substantially equal distances between adjacent clamps. Each wire as it is delivered is temporarily rigidly secured in proper position against said open clamps, and the latter are thereupon caused to move together, while simultaneously the intermediate portions of the wire spanning the spaces between adjacent clamps are bent and forced down or in between the latter, thus producing folds or loops therein, which are compressed between the faces of the clamps as they finally close together, whereupon the clamps are caused to release the loops to permit the finished stay to be withdrawn and ejected from the machine.

Referring to the `drawings by specific letters of reference, A designates asuitable machine-frame, and the letter B denotes adriving-shaft, to which power may be applied at a friction-pulley b, herein represented (more clearly in Fig. 2) as loosely mounted on the driving-shaft and adapted to be moved by a lever b into or out of driving engagement therewith, as by means of the clutch b2, so as to operate or stop the machine at will. As herein represented, the shaft B drives, through the medium of bevel-gearing c, a counter-shaft C, having a pinion c' thereon in gear with one of a pairof equalintermeshing spurwheels CZ and d', keyed or otherwise secured on the main driving-shafts I) and D', from which latter motion is transmitted to the various operative parts of the machine.

The main shafts D and D/ are provided with cranks E, secured one to each shaft and set, preferably, at such relation to each other that their opposite revolutions occur synchronously, and said cranks carry rollers e, which travel in operative engagement with a pair of oppositely, intermittently, and synchronously rocking actuating members or rocker cams F, from which, preferably through the medium of rocker members G, connected to said rocker-cams by suitable rods g, intermittent reciprocatory motion is transmitted to a series of loop-compressing clamps or jaws II, slidably supported between guides or ribs I at the upper part of the machine, Figs. 4, 7, and l0, and which in the present construction are arranged to separate and close or come together from and toward the middle of the series or from and toward an intermediate stationary clamp, (designated by the letter H,) the said movable clamps at each side of said stationary one being connected to the corresponding rocker members G by suitable connecting-rods g' and from which rocker-cams also similar reciprocatory motion is transmitted to a series of needles or loop-bending devices K, disposed midway between adjacent clamps and arranged to travel longitudinally therewith, said needles being herein pivotally mounted upon aseries of rockerarms K', slidably secured on a square or polygonal rock-shaft J, Figs. l and 7, which on rockingth us alternately depresses and elevates the needles, and the said slidable rocker-arms at each side of the said stationaryclamp being also connected to thelcorresponding rocker members G' by suitable connecting-rods g2. The connecting-rods g' and g2 are preferably of such length and secured to the rocker members G at such positions that the clamps are caused to separate at equal distances and to close evenly and the needles caused to maintain at all times substantially midway positions between adjacent clamps for` a purpose which will hereinafter appear, and the said rocker members G may consist of parallel bars rigidly secured together, to one of which bars of each member the rods g' may be secured and to the other bar the rods g2, both preferably by adjustable connections, as the sleeves Vgi", slidable on the bars and secured in place by set-screws or other suitable means. Outward movement or throw of the rocker members G, and consequently also separation of the clamps, may be properly limited by suitable buffers, as g, while inward throw of the members is of course limited by the closing of the clamps.

Each wire to be formed into a stay is temporarily rigidly secured in proper position upon or against the clamps G when the latter stand open or separated, and said clamps are then caused to move inwardly, while simultaneously the rock-shaft J is turned to depress the needles K, which engage and bend the intermediate portions of the wire spanning the spaces between adjacent clamps down or in between the same, thus producing loops or folds in the wire, which loops are compressed between the clamps when they finally close together, all in the manner hereinafter described.

The rocker-cams F are preferably of internal formation, being each constructed with confronting arc-shaped surfacesf, traversed ICO rocker-cam stationaryin such laterposition.

That one of the arc-shaped surfaces of each rocker-cam which the roller travels after throwing the rocker-cani to position to close the clamps H is preferably provided with a short raised portion or projection, as -f2,vrhich after such throw the roller passes over to force the member still-farther, thus shoving or impelling the said clamps-or blocks more closely together and causing them to compress or squeeze the loops of the stay just previously formed between them, while when the roller leaves said projection and travels onto the remaining arc-shaped surface there is permitted a slight reverse movement or backlash of the rocker-cam, and consequent slight reactive movement or separation between the clamps, which are then'caused to release the loops to permit the finishedstay to be withdrawn from the machine. In the construction herein represented the rocker-cams are l thrown outwardly, or to the position shown in Fig. 1, to separate the clamps, and inwardly, or to the position represented in Fig. 10, to close them, the rollers traveling in the directions indicated by the arrows, and it will be observed that by reason of action of the rollers against surfaces respectively nearer and more remote from the fulcrums of the rockercams said rocker-cams are moved more swiftly in .their voutward throws to separate lthe clamps and with greater power inl their inward throws to close said clamps and compress the loops of the stay, which arrangement is thus obviously advantageous.

The slidable clamps H, including the intermediate stationary7 member H of` the series, S0

may consist of. suitable blocks or heads, (shown in detail in Figs.13 to 18, inclusive,)

each of whichmay beprovided with suitablel extensions or bifurcations h, which slidably embrace the guides I. Said blocks or clamps are also preferably provided at their upper surfaces with upstanding projections or abutments h', against which each wire is lodged when delivered upon the clamps and firmly maintained during the' entire operation of forming the loops therein between said abutments, the blocks being transversely grooved or recessed, as at h2, to permit the entrance of hooks beneath the finished stay to withdraw the same from the machine, as illustrated in Figs. 11 and 12. The said abutments h of each clamp or block' are preferably disposed correspondingly obliquely, or

one slightly in advance of the other, as illustrated in Figs. 2 and 16, so thata wire forced against the abutments of the several clamps will be correspondingly deflected from its.

general alinement'acro'ss each block and oppositely deflected across the intervals between adjacent blocks, being thus held at adjacent sides of adjacent clamps at points one slightly in advance of the other. Consequently when the portions of the wire spanning the intervals between the clamps are bent down bythe needles lK asy the clamps move inwardly, Figs. 7and 13, the two .members of each bent or looped portion of the wire will incline from the needle to points one in advance ofthe other, and when the clamps finally close together the loops will thus be pressed between the same, with the two members of each loop lying in the' same vertical or transverse plane to the body of' the stay and the-intermediate straight portions of the stay diverging from and to corresponding members of adjacent loops, as illustrated in Figs. 12 and 14, whereby stays may be produced of the character represented in Figs. 21 to 23, inclusive, as mentioned in the objects primarily stated. It will be understood, however, that the abutments may be differently arrangedy and vthat stays of dif'- ferent character maybe produced. The said clamps or blocks may be further provided, preferably at corresponding sides kor faces throughout, with dat anvil plates or projections hg and atftheir'opposite sides or faces with similar con fronting anvil platesor projections h4, which latter are formed onlor secured to hinged or movable portions or faceplates h5 in said sides adapted when the clamps are closed to recede into recesses in loo the latter to release the loops of the stay, said A hinged or movable face portions h5 being preferably spring-pressed inwardly against suitable eccentric devices, such as the semicyliridrical portions of mutilated spindles h, journaled behind the hinged face-plates and nor-v mally maintained in position to hold the same outward, as shown Fig. 16, but adapted to be turned to permit-said face-plates to Iiap or move inward, as indicated in Fig. 17, in the present construction the said-spindles being jou rnaled in ytubular sockets at the bottoms of the clamps and provided at their lower protrudingv ends with short levers or projections k7, spring-forced against suitable pins or stops its tohold the face-plates outward, and having depending pins or studs hg, adapted to be simultaneously engaged b y the forked or bifurcated ends of aseries of push-rods to-simultaneously release the face-plates and permit them to'move inward, as indicated in Fig. 17. In the stay-making operation, the-wire being properly heldagainst the abutments h,"the loops are bent down by the needles K between the plates or projections h3 and 7t4of adjacent clampsand pressed or clamped between said plates when the clamps are forced together, as shown in Fig. ltwhereuponfthe hinged IIO face portions h move inward to release the loops and to permit the finished stay to be withdrawn. The confronting loop-compressing plates h3 and 71.4 are preferably vertically disposed for the purpose of forming the loops at right angles to the body of the stay, though it will be understood that said plates or likewise the adjacent faces of the clamps may be correspondingly obliquely disposed for the purpose of producing loops at other anglesv to the stay, if desired.

It will be observed that in the machine herein illustrated each clamp from end to end of the series is somewhat less in width than the preceding clamp, which arrangement is for the purpose of producing stays having their several loops disposed at successively-closer intervals, as shown in Fig.

' 2l, such stays being thus adapted for attachment to a series of parallel strand-wires arranged atcorrespondiugly-diminishing gages; but the construction may be varied to produce stays of different character, it being obvious that the intervals between the adjacent loops of the stay will be determined by the corresponding widths of the clamps,while the lengths of the loops will be determined by the distances the clamps are caused to separate.

To hold the wire firmly in position upon the clamps during the operation of forming the loops therein, a pair of wire grippers or fingers L may be pivoted at the outer sides of the abntments h' of each clamp, which fingers normally remain raised from the clamps, as shown in Fig. 4; but when the wire is forced hack under them against the abutment are immediately caused to bear down upon or to i grip the Wire, as illustrated in Fig. 7, in the present construction said grippers being provided with rearward extensions Z., which are slidably supported upon a bar or beam m, secured lengthwise to a rock-shaft M, journaled at opposite ends of the machine, and which on rocking thus alternately causes the grippers to grip and releasev the Wire in an obvious manner.

The rock-shaft M may be actuated by a lever N, connected to an arm m ou the rockshaft, Figs. 4 and 7, byasuitable connectingrod n, and said lever may' be operated by a cam N on one of the main driving-shafts, (here shown on the shaft D, Figs. 1, 6, and 19,) said cam being adapted to suddenly lift or move the lever to cause the grippers to grip the wire as soon as the wire is pushed against the abutments h of the clamps (by means hereinafterdescribed) to maintain said lever in position to hold the grippers down upon the wire during the entire loop-forming operation and then suddenly to drop or move the lever to release the grippers, as will be clearly understood by reference to Figs. 1 and 6.

The needles o'r loop-bending devices K, Figs. 4, 7, 13, and 14, which, it will be remembered, are pivotally mounted on the slidwith the wire at substantially the same instant v the clamps begin to move inwardly, continuing to lower them to bend the loops during such inward movement, While just before the clamps iin-ally close together the rock-shaft is oppositely moved to raise the needles in order to carry them away from the wire and to permit them to escape the approaching` plates or projections h3 and h4, between-which the loops are finally clamped and compressed. In order to properly guide the needles and cause them to bend the several loops of the stay in alinement, said needles may be controlled in their vertical movements by double crank-shaped devices 7c, which in the present construction are inserted through slots 7c* in the upper portions of the needles, their intermediate folds or bends embracing the latter and their ends slidably pivoted in apertured ears 7c3 on the grippers L to permit the clamps to lcome together without obstruction, said devices being normally maintained elevated in the slots by retractile springs 7a4, secured to the wire-grippers and to bends or return folds of the devices, as shown in Figs. 2 and 4. The said double crank-shaped devices thus serve to maintain the needles in their proper upright positions and to guide them in their descent to engage the Wire, and when the needles are drawn down to the fullextent of the slots k2 said devices, being thus encountered and rocked against force of their springs 7a4, impart a slight crank motion or forward throw to the needles during their further descent, as will be seen by reference to Fig. 7, causing them to bend the several loops in exact alinement. the needles before engaging the double crankshaped devices may be limited by movable side plates 705, extending across the upper' ends ofthe slots 7a2 and adjustable by means of screws 7c, as shown more clearly in Figs. 7 and 13.

The rock-shaft J may be actuated to alternately depress and elevate the needles by a lever O, which is herein represented connected to an armj on the rock-shaft by links o and o2 and an intermediate bell-crank lever o', Figs. 4 and 7, and the lever may be 0perated by a cam 0' on one of the main shafts, (herein shown on the same shaft D as the cam N', which operates the gripper-actuating lever N,) Figs. l, 5, and 19, said cam O being adapted to gradually lift or move the lever to Downward movement of IOO IOS

draw the needles down upon or into engagement with the wires by the time the clamps begin to move inwardly and to con tinne such movement to cause the needles to bend the loops while the clamps are moving inwardly and to suddenly drop orfoppositely move the leverto raise v the needles just before the clamps iinally close together, as will be clearly understood by reference to Figs. l and 5. It being necessary that the needles be raised instantly to escape the approaching plates h3 and h4 of the clamps, the action may be facilitated by a stout retractile spring o3, herein represented secured to the link o and to a rearward member of the machine frame, Figs. 4 and 7. L

The wires 2 to be formed intostays may be cut into proper lengths and presented from between inclined guide-bars P and P to an intermittent feed device,which delivers a wire upon the clamps at the proper period prior to each stay-making operation. The said feed device may consist of a longitudinal shaft Q, journaled in the lower extremities of the lower bars P', as shown more clearly Vin Fig. 7, and having secured thereon adjacent said extremities thin disks or collars Q, which disks are correspondingly provided with equidistant circumferential notches Q' and are partially embraced bycurved guards p, formed at the lower extremities of the upper bars P and terminating below the shaft. The guide-bars are preferably provided at adjacent edges with adjustable strips p2, between which the wires are supported on their way to the feed device and which may be properly adjusted to prevent crowding or crossing as well as to accommodate wires of different sizes. At each intermittent or partial rotation of the shaft Q one of the notches Ql of each disk is brought to register exactly with the spaces between the strips p2, and thus receive a wire, While atthe same time a wire previously received by other notches, having been carried around and past the lower eX- tremities of the guards @,is dropped therefrom upon the clamps, being directed to fall in proper position upon the latter and in front of the grippers L by suitable guides, as R and R', the former of which guides are herein rep` resented mounted on the front clam p-supporting slide I and the latterY upon the clamps themselves. The thin notched disksQ are employed in preference to devices of greater thickness in order to facilitate admission of the wires into the notches Q' thereof, since in a delicately-constructed apparatus any curve or bend in the wire might retard or prevent its entrance into notches of any substantial length. To fix the disks to th@ shaft and to provide sufficient bearing within the guards p, said disks may be securedto collars Q2 on the shaft having circumferential cut-away portions, as Q3, at points corre-. sponding to the notches of the disks to prevent interference with the wires, as shown more clearly in Fig. 9. As ameans for inter-A mittently rotating the feed device the shaft Q may be provided with a ratchet-wheel Q4,

i Fig. 8, rigidly secured thereon and having its teeth, which correspond in number with the notches of the disks Q, successively engaged by a spring-pressed pawl Q5, carried by a rocking lever QG, which in the present construction is represented as loosely mounted on the shaft Qbetween the ratchet-wheel and a collar Q7 and connected by-a cord or rope QS, Figs. l, 2, and 4, toa crank Q9 on one of the main shafts, herein shown on the shaft D, said lever being maintained against pull of the cord by a retractile spring Q10, which draws down upon a tailpiece of the lever, or by other suitable means. At' each revolution of the crank Q9 the lever is thus moved by force of the spring when the cord is slack to carry the pawl past the ratchet-tooth nextto be engaged and oppositely moved by pull of the cord-to partially rotate the feed device, and for econonly of time the arrangement is preferably such that thefeed device is caused to drop a wire upon the clamps simultaneously as the latter separate..

Mounted on the machine at one end of the series of clamps H is a stationary upright plate or abutment S, and at the opposite end a similar ypivotal or movable plate or butter S' is'spring-impelled toward the abutment S, but held against force of the spring by connection to a rocker-arm s on a rock-shaft T,

which may be longitudinally disposed at the front of themachine. As each wire is delivered upon the clamps the said rock-shaft T is turned to permit the butter to strike the end of lthe wire and force it endwise against the'opposite plate orabutment S, being immediately oppositely turned to draw back the butter as soon as the grippers grip the wire, and thus each wire is held in the same position upon .the clamps, and the loops of Athe several stays are thereby formed at exactly corresponding points.

AThe rock-shaftT carries a series of upstandiug rocker-arms t, to which are pivotally secured a series of push-rods t', which the clamps next-the rearmost abutments of each,V as shown in Fig. 2, whereby the wire when forcedagainst the said abutments will be properly obliquely deflected across the several clamps and oppositely deflected across the intervening spaces for the purpose before mentioned. f

The rock-shaft T may be actuated by a lever-U, which in the arrangement herein represented is connected to an arm t2 onthe shaft by links u and u2 andan intermediate bellcrank lever n', Fig. 4:, and the lever may be operated by f'a cam U onone of the main IOO IIO

shafts, herein shown on the shaft D', Figs. 1 and 20, said cam being adapted to lift or move the lever immediately after delivery of a wire upon the clamps to cause the butter S' and push-rods i' to force the wire into proper position upon the latter and then to drop or oppositely move thelever to immediately retract said butter and push-rods as soon as the wire is gripped by the grippers L. A second rockshaft V, also longitudinally disposed at the front of the machine,carries a series of rockerarms QJ, to which are pivotally secured a series of push-rods c', having forked or bifurcated ends, as o2, and which rods are herein represented slidably supported on guides c3 on the lower side of the upper front beam or member of the machine-frame, Figs. 1, 4, and 7. After each stay-making operation, the clamps being closed and pressing the loops of the finished stay between them and the grippers being released, the rock-shaft V is immediatel y rocked to pu sh the said p usb-rods back beneath the clamps and against the pins 7L", Figs. 16 and 17, thus turning the spindles h6 and causing the hinged face-plates h5 to sim ultaneously move inward to release the loops and permit withdrawal of the stay.

rThe stay may be withdrawn by hooks 1U on rods XV, supported upon the upper part of the machine-'frame and pivotally connected to arms llo' on the rock-sh aft V, which on rocking to push the devices c' back against the pins hgsim ultaneously pushes the hooked rods NV back under the stay, as represented in Figs. l1 and 12, so that when the shaft is oppositely turned the stay is engaged by the hooks and withdrawn from the clamps. The said hooked rods may be disposed to engage the wire at the sides of the outermost clamps when the latter come together or at intermediate points by passing into the transverse slots or recesses h2, formed below the wire in the upper surfaces of the clamps. The rods W may be provided with side pins or projections fm2, which when the rods are pushed back to engage the stay trip or snap under inclined pawls or dogs w3, mounted in suitable supports, as 104, at the sides of the rods and spring-maintained down against the machine-frame; but when the rods are moved forward said pins encounter and ride up the inclined pawls, as indicated by the dotted lines in Fig. l1, thus throwing the hooks suddenly forward and withdrawing the ,stay before the movable face-plates 77.5 snap back again against the loops and also forcibly ejecting the stay, which may fall upon suitable inclined rods or guides X and drop from the machine.

The rock-shaft V may be actuated by a lever Y, Figs. 1 and 4, which may be connected to an arm c4 on 'the shaft by a rod or link y, and said lever may be operated by a cam Y' on one of the main shafts, herein shown on the shaft D', said cam being disposed to lift or move the lever immediately after each stay-,forming operation to cause the faceplates h5 to recede or move inward and release the loops and immediately oppositely rocked to cause the hooks to withdraw and eject the stay, as will be clearly understood by reference to Fig. 1.

The operation of the machine will be apparent from the foregoing description taken in connection with the accompanying drawings. In Figs. 1, 2, and t the machine is represented with its operative parts in the relative positions assumed immediately after outward throw of the rocker-cams F to separate the clamps H, during which movement the feed device has been intermittently rotated to deliver a wire 2, the same falling upon the clamps in about the position shown in Fig. 4. The operating-rollers e, carried by the cranks E on the main shafts, having thrown the rocker-cams, have now started up the outer arc-shaped su rfacesfthereof to maintain said members stationary in their extreme outward inclined positions, thus holding the clamps separated, and during such inactive travel of the rollers the following movements suecessively occur, viz: The cam U', Figs. l and 20, instantly lifts or moves the lever U, thereby turning the rock-shaft T to cause the butterS' to strike and push the wire endwise against the plate S and the push-rods t' simultaneously to force said wire lengthwise under the grippers L and-against the abutinen ts h' on the clamps, whereupon, the wire being thus secured in proper position against the abutments, the cam N' immediately lifts or moves the lever N, thereby turning the shaft M to raise the beam on, upon which rest the rearward extensions of the grippers L, and thus forcing said gripper-s to bear down upon or grip the wire, and thereupon the lever U again is dropped or oppositely rocked to retract the butter S' and withdraw the pushrods t' from engagement with the wire, and during the successive movements just described the cam O' may begin to gradually lift the lever O, continuing such action during the remaining inactive travel of the rollers e, (as well during the succeeding opposite or inward throw of the rocker-cams F to close the clamps,) thereby gradually turning the rock-shaft J in a direction to depress the needles K, which are drawn down to engage the wire at substantially the same instant the rollers e pass to positions to oppositely throw the rocker-cams F to close the clamps, as indicated in dotted lines in Fig. 10. The rocker-cams are now moved by the rollers to their said opposite inclined positions, (represented in full lines in Fig. 10,) thereby moving inwardly and closing the clamps and likewise moving inwardly with the clamps the slidable rocker-arms K', which support the needles K, so that the needles are caused to engage the wire always midway adjacent clamps, and during such throw, while the said clamps are being brought together, the cam N' still maintaining the lever N in position to keep the grippers irmlydown upon IOO IOS

IIO

the wire, the cam O continues, preferably acceleratively, movement of the lever O to further depress the needles, thusbending or folding the wire in between the approaching clamps in the manner v already explained, Figs. 7 and 13, said cam suddenly dropping or oppositely moving the lever to elevate instantly the needles to clear the plates h3 and h4 ofthe clam ps just before the latter close or come finally together to clatnp and press the loops between them. Having thrown the rocker-cams to position to close the clamps against the loops, the rollers c on leaving the upper recesses f/ ot'- said members now pass over the short projections f2, thereby moving the rocker-cams slightly farther inward, and

r consequently causing the clamps to squeeze or compress the loops more tightly between them, after leaving which projections and thereupon permitting a backlash of therockercams and consequent slight reaction between the clamps the roller traverses the remaining inward arc-shaped surfaces f to .maintain the clamps closed, during which inactive travel the following movements occur, Viz: The cam N' drops or moves the level' N, thereby oppositely turning the rock-shaft M to lower the beam m, and thus release the grippers from the Wire, and the cam V thereupon raises and lowers or vibrates the lever Y, thereby rocking the rock-shaftVto move the push-rods c' beneath the clamps. to move the spindles h6, so to permit the face-plates h5 to move inward and release thel loops and the hooks w to withdraw and eject the tinished stay.

It is obvious that the several clamps at each side of the intermediate stationary block ber ot clamps may, if desired, be connected to a single one of the rocker members F, and thus arranged to alternately open and separate from and toward the end instead of the center of the series, one of the main drivingshafts being then dispensed with andthe several mechanism-actuatinglevers being all operated by cams orother devices from a single driving-shaft, though the arrangement herein represented is preferred, since the action of the clamps at each side of the stationary block is counterbalanced by the action of the clamps at the opposite side, and, furthermore, each olamplof any given number and in the same interval of time is required to more a less distance, and consequently with less speed, thus securing more time for the oper- ItisV ation of the needles with the same rate of rotation ot the driving-shaft.

The invention is also capable ot embodiment in other forms andy susceptible of various modilieations in rdetails of construction and arrangement of parts, and hence we do not desireto be limited to the particular construction and arrangement herein illustrated.
